WEST Coast star Nic Naitanui is set to miss Saturday's clash against Greater Western Sydney after being offered a one-match suspension for a dangerous tackle on Port Adelaide's Karl Amon.

Naitanui tackled Amon from behind midway through the final quarter of the Eagles' 42-point victory at Optus Stadium on Saturday and, as the Power player fell to the ground, landed directly on top of him.

Amon suffered a concussion in the incident and is in doubt for the Power's round eight clash against Adelaide at Adelaide Oval on Saturday. He will be assessed during the week.

Match review officer Michael Christian assessed Naitanui's tackle as careless, medium impact and high contact.

"This was a dangerous tackle, which we deemed to be unreasonable in the circumstances in that he drove Amon into the ground with excessive force while Amon was in a vulnerable position with his arms pinged," Christian said on Monday afternoon.

The match review boss said Port Adelaide's medical report had been a key factor in him grading Naitanui's tackle as medium rather than low impact.

Naitanui has also been hit with a $1000 fine for attempting to trip Jasper Pittard in the third quarter of Saturday's game, while Power defender Dougal Howard has been fined $2000 for rough conduct against Josh Kennedy after a careless spoiling attempt when he collected the Eagles spearhead with a knee to the glute.

- Carlton's Dale Thomas ($2000) for rough conduct after bumping Adelaide's Jordan Gallucci.

- Richmond's Nick Vlastuin ($1500) for misconduct against Docker Ed Langdon.

Meanwhile, Melbourne's Jesse Hogan has been cleared of staging after he won a free kick against Jake Carlisle during Sunday's clash at Etihad Stadium.

Based on goalpost vision, Carlisle turns toward Hogan and makes contact with an open hand to the throat area.
